3D printing buildings without cement
Briefly

"We developed a robotic tool and a method that could take common material, which is the excavated material on construction sites, and turn it back into usable building products, at low cost and efficiently, with significantly less CO 2 than existing industrialized building methods, including 3D printing," said Lauren Vasey, one of the researchers and an SNSF Bridge Fellow at ETH Zurich.
Impact printing utilizes Earth-based materials such as sand, silt, clay, and gravel, which are abundant, recyclable, and readily available at low costs, making it a sustainable alternative.
